    • Original 255.0 kB
    • After minification 251.5 kB
    • After compression 37.6 kB

    • Original 259.3 kB
    • After minification 258.3 kB
    • After compression 96.3 kB

    JavaScript optimization

The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 163.1 kB or 63% of the original size.

    • Original 14.8 kB
    • After minification 12.1 kB
    • After compression 2.1 kB

    CSS optimization

Possible request optimization













Normal result

IP address uses IP address which is currently shared with 4 other domains. The more sites share the same IP address, the higher the host server’s workload is. It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.

Language and encoding

Poor result


RU ru language flag


N/A  language flag





Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise can be misinterpreted by Google and other search engines. Our service has detected that Russian is used on the page, and neither this language nor any other was claimed in <html> or <meta> tags. Our system also found out that main page’s claimed encoding is windows-1251. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.

HTTPS certificate

SSL Certificate has no SSL certificate. Web browsing can be safer with HTTPS connection, so we suggest that it should be obtained for this site.

Normal result

Visitor World Map

Country of origin for 89.5% of all visits is Russia. It lies approximately 3630 miles away from the server location (France) and such a long distance can negatively affect website speed, as it takes some time for data to travel back and forth between those places. That’s why one of the best ways to speed up page load time for the majority of users is moving the server to Russia or just closer to the user base.

Social Sharing Optimization

Open Graph description is not detected on the main page of Proshkolu. Lack of Open Graph description can be counter-productive for their social media presence, as such a description allows converting a website homepage (or other pages) into good-looking, rich and well-structured posts, when it is being shared on Facebook and other social media. For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
